Pneumatic pneumatic - valve Choose pneumatic valve pneumatic valve driven by nature

the electric pneumatic valve electric pneumatic valve pneumatic valve is a common way of driving, often call this kind of drive of drive pneumatic valve electric actuator, pneumatic valve electric actuator are as follows: the characteristics of opening and closing fast, can greatly shorten the time needed for pneumatic valve opening and closing; Can greatly reduce the labor intensity of operators, especially suitable for high pressure, large diameter pneumatic valves; Suitable for installation in the manual operation can't or difficult to close position, easy to realize remote operation, and the installation height with unlimited; Be helpful for the automation of the whole system; Than air and hydraulic power source is easy to get the wire laying and maintenance than compressed air and hydraulic pipeline is much simpler. The disadvantage is that the structure is complex, pneumatic valve electric actuator used in damp places more difficult, when used in explosive medium, need to be adopted and isolation measures. Pneumatic valve electric actuator driven by pneumatic valve type is different, can be divided into two major categories of Z type and Q type. Z type pneumatic valve electric device output shaft can turn out a lot of laps, suitable for pneumatic drive gate valve, globe pneumatic valve, pneumatic diaphragm valve, etc. ; Q type pneumatic valve electric device can only output shaft rotation. , it is suitable for driving cock pneumatic valve, pneumatic ball valve and butterfly valve, etc. According to the protection type are normal, flameproof ( With type B said, heat-resistant ( Expressed in R and integrative type ( Namely, outdoor, anti-corrosion, explosion-proof, expressed in S. Pneumatic valve electric device by actuator (commonly Reducer, electromotor, stroke control mechanism, torque limit institutions, manual - The opening of the electric switching mechanism, indicator, etc. Pneumatic and hydraulic pneumatic valve pneumatic pneumatic and hydraulic valve is a certain pressure air, water or oil as the source of power, using cylinder ( Or the movement of the hydraulic cylinder and piston to drive the pneumatic valve, pneumatic air pressure is less than. MPa, hydraulic pressure or oil pressure. MPa~MPa。 Or pneumatic diaphragm valve; Back to the transformation of gas and liquid driving device used to drive device used to drive the pneumatic ball valve, pneumatic butterfly valve or cock pneumatic valve. Driving force of the hydraulic device, pneumatic valve is suitable for driving large diameter. Used to drive the cock, such as pneumatic valve, pneumatic ball valve and butterfly valve, must transform the reciprocating movement of the piston rotary movement. In addition to adopt cylinder or the piston of hydraulic cylinder to drive, don't have driven by pneumatic membrane, because of its stroke and the driving force is small, it is mainly used for adjusting the pneumatic valve. Manual pneumatic valve manual pneumatic valve is the most basic way of pneumatic valve. It includes using the handwheel, handle or wrench direct drive and driven by transmission mechanism, two kinds. When the pneumatic valve and torque is bigger, can through the gear or worm gear drive, to achieve the purpose of ellipsis. Gear transmission points straight tooth cylindrical gear and taper gear transmission. Gear reduction ratio is small, be applicable to the pneumatic valve, pneumatic valve gate and globe worm gear deceleration is larger, apply to cock shem, pneumatic ball valves and butterfly pneumatic valve.
